Check Digit Verification of cas no

The CAS Registry Mumber 844501-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,5,0 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 844501-71:
(8*8)+(7*4)+(6*4)+(5*5)+(4*0)+(3*1)+(2*7)+(1*1)=159
159 % 10 = 9
So 844501-71-9 is a valid CAS Registry Number.
